After the participants were corrected the refractive error, vision training is conducted to compare with accommodative function of children who do not received vision training. Besides, the study analyzes the changes in accommodative function and refractive error diopter, applies to exploring the differences between visual functions and refractive error diopter changes, as well as feasibility of vision training.This study revealed that participants in experimental group of auto flipper were obviously improved accommodative amplitude and facility. Participants in experimental group are tested by push up method.As for minus lens test of amplitude of accommodation in experimental group, average value of right eye increases 0.343D, and left eye increases 2.374D. In addition, compared with control group, amplitude of accommodation is significantly improved. In terms of degree variation, average value of right eye in experimental group is -0.0319D,and the left eye is +0.0271D. Average value of right eye in control group is +0.0625D, and the left eye is -0.281D. After the training, average value variations in experimental group are relatively more stable than the control group. After the training, accommodation facility of participants in experimental group increases significantly. On average, the accommodation facility in experimental group increases 6.815cpm Hence, dynamic accommodation of distance and near vision is obviously improved, which is conducive for participants to identifying the definition of target objects and reduce the time of focusing.
